Richard Garland, chief executive of Janus International and managing director of Janus Global Adviser, has resigned following the investigation by the Securities and Exchange Commission (SEC) into mutual fund irregularities.

Garland will be replaced by Erich Gerth, previously vice president and national sales director of Janus Global Adviser. Gerth assumes responsibility for Janus' worldwide broker-dealer and independent adviser sales functions and the company's international institutional sales business. Gert joined Janus in July this year from Goldman Sachs Asset Management. He reports to Mark Whiston, group chief executive.
